FM MATRIX REGISTER
This register is used to select the proper dematrixing characteristics as appropriate for the standard of the received
carrier and the related sound mode identification.
Table 28 Subaddress 11 (note 1)
Note
1. The default setting at power-up is 0000 0000.
Table 29 Dematrixing characteristics
Notes
1. CH1 input: audio signal from FM channel 1.
2. CH2 input: audio signal from FM channel 2.
3. For stereo Korea the dematrix applies 6 dB attenuation (see Table 7).
